This paper summarises the text-to-speech system that has been developed during the last years in the Speech Group of the Universitat Politccnica de Catalunya (UPC). The paper emphasises the parts of the system which are ...

The design and development of a broadcast FM modulator with a RDS (radio data system) encoder is presented. The system is fully coherent with the modulated RF frequency synthesized in the 875-108 MHz frequency band with ...

A wideband channel sounder to characterize the HF radio channel is described. Based on a pseudorandom sequence technique it allows the measurement of the complex impulsional response of the channel with time and frequency ...

This paper presents a new mechanism that combines the flexibility of an access protocol such as ISMA-DS/CDMA with the ability of a polling mechanism to provide a specific bound for the access delay. This protocol is proposed ...

The authors are interested in the comparison of several kinds of methods for fundamental frequency estimation and GCI (glottal closure instant) detection. These methods operate in various domains (time-, frequency- or joint ...

Although different methods for NOAA AVHRR image navigation have already been established, the multitemporal and multi-satellite character of most studies requires automatic and accurate methods for navigation of satellite ...

Layered representations of video sequences, originally introduced in [1], are important in several applications. Specifically, they are very appropriate for object tracking, object manipulation, content-based scalability ...

The equalization of constant amplitude signals is considered in the scope of this paper. A criterion based on the probability density function (pdf) of the signal of interest is proposed. The objective is to derive a ...

An improved adaptive filter for eliminating periodic vibrations of unknown frequency in rotary machinery is presented. The proposed canceller is based on a usual bank of digital adaptive notch filters, each filter tuned ...

The surface current distribution of a Sierpinski fractal antenna shows a self-similar behaviour determined by the self-similar properties of its geometry. The application of infra-red thermography to electromagnetic near ...

The activity of the EEF group in the TMR European Project Radar Polarimetry: Theory and Applications will be presented in this paper. We have developed new polarimetric-interferometric retrieval algorithms and enhancement ...
